A Mercedes-Benz board member Wednesday denied claims the company is actively resisting efforts to organize workers at the automakers Tuscaloosa County manufacturing plant.

Reuters is reporting the company, however, would not comment on whether it has hired a specific “union busting” consultant as it prepares for a vote next week on employees joining the United Auto Workers (UAW).

The Mercedes-Benz group “respects the decision of the employees to establish a trade union organization, and it will monitor the election process and will make sure that every team member has the opportunity to cast a secret vote,” board member Renata Jungo Bruengger said at the annual shareholders’ meeting in Germany.

Next week’s vote will begin on Monday, with final results due on Friday.

The news agency reported that Jeremy Kimbrell, a union supporter at the Vance factory, said Mercedes had hired anti-union consultancy RWP, which has been linked to anti-union campaigns with companies such as Amazon.

A representative of Germany’s Association of Critical Shareholders (DKA), representing small investors on environmental, social and governance issues, read out the claims at the meeting.

Mercedes would not comment on whether it had hired RWP, and RWP’s CEO also declined to comment on whether Mercedes was a client.

In April, the UAW announced it was bringing charges against Mercedes in Germany for violating a law that forbids companies from non-compliance with labor protections, as well as discrimination and withholding of wages.

UAW supporters began signing up employees late last year and reached a supermajority of about 70% in April. Next weeks’ vote comes after UAW waged a successful campaign to unionize Volkswagen’s Chattanooga plant.
